Be it known that I, THoMAs PARKiiR, a

subject of the King of Great Britain and Ireland, residing atgSevernHouse, Ironbridge, 1 Salop; England, "have invented certain new anduseful Improyements-Relating tpatl e; Destructive Distillation, ofi'BitumihousgC-oal or Similar carbonaceous Subsimilarcarbonaceoussubstance and par- 'HNQ. 865,724 26/1/07 that is to-sayto an apparatusfor the partial destructive dist1llat1onof coal at a low temperature arrested at the pointwhen illuminating jgas f The invention has for itsobject to effect such a distillation. with economy and efli ;.c1.en cyand m such manneras to produce a.

thoroughly homogeneous product Without any wastage"duev to insu-flicientdistillation of any part of themass. I

According'to the invention IemplOy fine coal which is chargedintovertical retorts so that'its volume is sufficient completely to 30f fillthe retorts and so that when subjected 1 to heat in the process. ofdistillation. the charge is compressed and. may fall out of the .retortsand thus a fuel produced that is hard and denser I effect thedistillation of such substance within vertical retorts of smalldiameter, that is to sayof about from A to '6 inches internal diameterand I apply {heat uniformly around the retorts'so that tthe distillationtakes'place toward the cen- 4O ter of the charge in the retortsbygradual penetration and" the whole mass. uniformly t tdistilled 'so thata homogeneous and uni-' iiorm product results with no wastage and awithout the necessaryinsuflicient distillation and carried withincommon,top and-bottom fittings. The topfitting .I providerwith-a series ofapertures for the reception of the ends of the retort tubes, andcentrally above the. series of" retort tubes ,I arrange the chargingaperture withinv a surmountin hood so that allrth'etubes may be filleices, of. whiclrthefollowing is a specifil l l .I I l Thisinvention"relates to the partial destructive distillation of bituminouscoal or.

through.- same charging apert-ure, and

little distance below the extremity, so that the flange may engage-onthe under-side of the top fitting e,' there being a clearance providedat flbetweenthe' upper end of the rethe fitting into whichlsuitableluting may be introducedso that thus the upper ends position with agas-tight joint) t The. retort tubes a are provided with a taper bore ofa diameter at their u per extremitiesv ofabo'ut 4-} inches and adiameter of about inch more at their lower extremities and thejlowerextremity ofeach tube I advantageously form witha conical face 12 for'se ating1upon a corresponding conical face provided on an inwardlyextending flange g protruding in the respective apertureof the bottomfitting 11. Upon the top fitting @I provide a hood :5whichadvantagcously contracts'inwardly toward its upper extremityleaving an aperture 1: sutli .ciently large for charging the severalretort tubes carried in the respective set of top and bottom fittings,and this aperture k is closed closed gas tight by means of a lever mpivoted 1n a -bracket on the hood, whichcover is pivotally carried bythe lever m, and is tightly closed by means of a bolt and nut. An outlet0 is formed laterally in the hood for the gas which passes up from allthe tubes of the battery unit.

hinged at s, and capable of being brought down by suitable means forthedischarge of 'the mass after partial distillation.

-- The retort tubes are so disposed with relation-to each'other as toleave interstitial In carrying" the invention into effect I. provide theupper extremity b of .the retort tubes" awith an outwardly extendingshoulder d andalaterally extending flange esom'e of the, retort tubesmay be firmly secured inf by 'a cover Z which may advantageously beQspeeiiication of- Letters Patent; Patented N p V, 23, 1909. a flicatioifiieamay 3,1909, Serial No. 493,685. f

I charge the respective batteries ofretort tubes with coal whichI'fi-rst pulverize prefv erably by passing the coal between grindingcharging '15 of the sire'to secure by Letters atent is rollers, and Ifill each set ofretort tubes by fine or pulverized coalthrough thecharginig'naoerture [a so that thus the volume e 'or pulverized coal"almost completely fills the-retorttubesand thus the partialdistillation takes place under compression' due to the weight of thedensechar e.
